MACHINERY FOR HEADING BOLTS, 85o.

Specicaton of Letters Patent No.

T aZZ 'whom it '1n/ay conce/rn.'

Be it known that I, EDWARD PAYE, of the city and county of Albany, inthe State of New York, have invented a new and useful Machine forHeading Bolts, Spikes, Rivets, &c.; and I do hereby declare that thesame is described and represented in the following' specification anddrawings The nature of my invention consists in a permanentrpivot with ahole in the center to which a die is fitted against which die the end ofthe rod to be headed is driven while it is held in a pair of jaws closedby a cam, and connected to a sliding hammer traversing upon rods or wayspressed back by cams and forced forward by springs so as to upset theend of the rod held in the jaws by striking it against the die in thepivot at the same time the head is squared by four sliding hammers whichtraverse in scores across the end of the pivot, being operated bygrooved cams in a collar which is tted to turn on the pivot which collaralso carries the cams which press back the sliding hammers.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation, referring to theaccompanying drawings in 301 which the same letters indicate like partsin each of the figures.

Figure 1, is a plan or top view. Fig. 2 is a sectional elevation throughthe line e, s, of Fig. 1. Fig. 3, is an elevat-ion of the front end-someof the parts are represented as broken 0E to show others.

A A is a strong frame made in the form represented supported by the legsB B. The head stock C is fastened to the frame by the bolts b b and issupported by the projections a a. The head-stock C has the projection orpivot D cast with it, with a hole in the center for the die E, which isfitted to it and secured by the nut 0. The pivot D has two scores acrossthe end at right angles to each other one of which is seen at F.

In each of these scores there is a sliding hammer Gr-(see a sideelevation Fig. 4)

which hammers are forced forward, that is the two which stand oppositeto each other, at the same time by two cams in the collar H, which isfitted to turn on the pivot D,

one of which cams is represented at I. The

sliding hammers Gr are drawn back by the pivot eZ which extends into thegroove J in the collar H. The face plate K fastened to 9,506, datedDecember 28, 1852.

the pivot D by the screws e e holds the slid lng hammers Gr in thescores F; this face plate also ts a rabbet in the collar H and holds iton the pivot D.

The collar I'I has the gear L on its back end which gear is turned andalso the collar by the gear M on the shaft N to which shaft a gear orpulleys may be applied so as to communicate the power requisite tooperate the machine. The shaft N turns in a box on the top of thehead-stock C and in a box on the stand O which stand is fastened to theframe A; and a fly wheel P is fastened to the shaft N to equalize themotion. The stand Q is fastened to the frame ik and supports the ends ofthe rods R R the opposite ends being supported by the headstock C asrepresented. The traversing halnmer S is itted to slide on the rods R Rand has the stud T fastened to it with a friction vwheel f in the endagainst which the cams U U act and press the hammer S back it beingforced forward by the spiral springs V V on the rods g g which rods arefastened into the end of the fralne A; the spiral springs V T actagainst the end of the frame AA and the cross-head VV fastened upon thetraverse rod X by the pin L, which rod X extends through the hamlner Swhich is fastened to it by the screw i, and through the arm Y fastenedto it by the screw 7' and pin 71;, and the end of the frame fr in whichit traverses to operate the hammer S which hammer has a cavity in thetop to which the jaws Z Z are fitted, which jaws have a score in each ofthem to fit the rod of the bolt m; the jaw Z is pressed back to theposition represented by dotted lines by the spring 711 placed betweenthe on the pin p also represented by dotted lines in Fig. 1. The jaw Zis forced up to the jaw Z by the cam g on the end of the lever 7 whichlever vibrates upon the screw s in a cavity fitted for it in the hammerS. rIhe rod of the bolt m is stopped by the arm Y so as to form the boltof the desired length the arIn being adjusted to the proper position onthe rod X for that purpose. The gage or stopt traverses in the stand uis fastened to the frame A. It is raised by the spiral spring QJ so asto stop the hammer S and is drawn down by the lever w which may bedepressed by the foot whenever it is desirable to' release the hammer Sto head a bolt.
